30 plays here - i think i exhausted every possible way of combining the numbers in that column to ensure a box hit (horiz,vert,diag,corners,zig zag,adjacent,criss cross,etc.....

I don't see any mistakes with the chart and how you worked it, assuming you wanted to include that many numbers to play. You picked the right last drawn number (690) and you picked the right column to use (the only column, with 690 connected).

Thanks to all: I put lots of work here (long hours) but it works. To narrow down- you can do this, go back to a chart I posted here a while ago about pairs from the last two hits and find the hit from those pair created from the last two draws.
